Be it known that I, DANIEL SNELL, of Springfield, in the county of Clarke and in the State of Ohio, have invented certain new and useful Improvements in Tumbling-Shaft; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a tumblingcentral bore of the box A is placed a round head, B, provided with lugs or ribs b I fitting in the grooves a a. In the center of the head B is secured a rod, 0, which passes out through a bearing-box, D, placed in the end of the box A. This bearing-box is made to fit the end of the main box A, and provided with lugs or ribs 01 d to fit in the grooves a a. In the other end of the main box A is secured a forked coupling, E, to connect with the shaft of the power.
